I've really enjoyed the sound of the RTi70/CSi40 front stage in my HT. However, I've recently discovered that the tweeters in the RTi70s are not working. I'm looking into replacements with Polk CS. However, we built a house last fall and are considering moving to in-wall/in-ceiling speakers in the HT when we purchase a tv to mount over the fireplace. So what Polk in-wall/in-ceiling products have a similar sound to the RTi70s? The other question I have is the ceiling in the room where the HT is located is 14'. Since the wall for the front stage is an outside wall with two windows, a fireplace, and sprayed insulation I'll have to place in-wall speakers about 11-12' up. Would I be better off with in-ceiling speakers in this case?
Here is a picture to give you and idea of what I'm talking about.
